Setting-up ETH ethernet on a custom carrier with i.MX6UL

[slopez]

Hi,

I'm setting up a custom carrier board made in my company with one TQMa6UL2-AA i.MX6UL based on evaluation board of TQ stka6ul. I'm trying to starting the ETH interface with one image of linux generated with Yocto using the TQ bsp.

In u-boot I could see the interfaces:
=> mii info
PHY 0x00: OUI = 0x01F0, Model = 0x0F, Rev = 0x01, 100baseT, FDX
PHY 0x01: OUI = 0x01F0, Model = 0x0F, Rev = 0x01, 100baseT, FDX

However, en Linux I couldn't see nothing. I don't know how I could fix this problem, I suppose the Linux kernel can't recognize the PHY but I don't know why.

Could anyone help with my problem?

Regards,

Hi slopez

one can recheck dts file if fec interfaces are enabled, like on below

follow linux documentation on https://support.tq-group.com/en/arm/tqma6ulx

Best regards
